DAY 6 3. Aperture - Function: The aperture is an opening in the lens that controls how much light reaches the sensor. It’s measured in f-stops (e.g., f/1.8, f/2.2). - Mobile Specifics: - Smartphone apertures are fixed (no adjustable diaphragm like DSLRs), typically wide (f/1.5–f/2.2) to maximize light in small sensors. - A lower f-number (e.g., f/1.5) means a wider aperture, allowing more light for better low-light performance and a shallow depth of field (blurry background). - Impact on Photos: Wide apertures create natural bokeh in portraits and perform better in dim conditions but may struggle with sharpness across the entire image in bright light. - Tip: Use portrait mode to enhance the shallow depth of field effect for subject-background separation, especially on phones with wider apertures.

DAY 5 HOW A SMARTPHONE CAMERA WORKS A smartphone camera is a compact, highly sophisticated system that combines hardware, software, and computational photography to capture images. Unlike traditional DSLR or mirrorless cameras, phone cameras rely heavily on software to compensate for their small physical components. Here’s a detailed look at the key elements and how they work together: 1. Lens - Function: The lens is the glass element that focuses light onto the camera sensor. It determines how much light enters and how sharply the image is captured. - Mobile Specifics: - Smartphone lenses are small (often 4–8mm in focal length) and fixed, with a wide aperture (e.g., f/1.8) to gather more light in a compact space. - Most phones have multiple lenses (e.g., wide, ultrawide, telephoto) with different focal lengths for versatility: - Wide (24–26mm equivalent): Standard lens for general photography.

DAY4 How Resolution Affects Picture Quality in Mobile Photography Resolution refers to how sharp, detailed, and usable your smartphone photos are. Here’s how it affects mobile photography: 1. Detail and Sharpness - High Resolution (e.g., 48MP): Captures fine details like textures, patterns, or distant objects, ideal for zooming in or cropping without losing clarity. For example, a 48MP photo of a landscape will show individual leaves or blades of grass clearly. - Low Resolution (e.g., 2MP): Results in less detail, making images appear blurry or pixelated when zoomed or enlarged. Pixelation occurs when individual pixels are visible, creating a blocky look. Example: A high-resolution photo of a flower taken with a 108MP camera will reveal intricate petal details, while a low-resolution version (e.g., 1MP from an older phone) will look fuzzy when zoomed.
